Abstract

The invention discloses an enameled aluminum wire winding inductive component, which comprises a magnet and a winding. The winding consists of a framework and an enameled aluminum wire, the enameled aluminum wire is enwound on the framework, the head end of the enameled aluminum wire is connected with a supporting leg, and the supporting leg is wrapped by soldering liquid to solidify a welding head. A preparation method comprises the following steps: putting metallic tin into a tin furnace of an ultrasonic aluminum welding machine, raising the temperature to between 350 and 420 DEG C to melting the metallic tin, and continuously wafting nitrogen to tin liquor by a nitrogen generator above the tin furnace to isolate oxygen in the melting process; and putting the supporting leg of the winding into the tin furnace to paste on the tin liquor under the vibration of ultrasonic waves, and cooling and solidifying the supporting leg. The enameled aluminum wire winding inductive component can be welded conveniently and firmly and is a perfect enameled aluminum wire winding inductive component; and because the preparation process of wrapping the tin liquor outside the supporting leg of the winding is performed under the action of ultrasonic waves and under the condition isolated from the oxygen by using the nitrogen, the technical problem that in the prior art the metallic tin is oxidized in the melting process is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of inductive components and relates to an enameled aluminum wire winding inductive component and a preparation method thereof. Background technique [0002] The inductance components in the prior art include magnets and windings. The windings are composed of skeletons and enameled copper wires, and the head ends of the enameled copper wires are connected to the legs. The preparation method is to stick the solder liquid on the leg connected to the head end of the enamelled copper wire on the winding, and wrap a layer of tin solder layer coat on the leg after solidification; the solder liquid is made of metal tin and placed in an ordinary container. Melted at high temperature. Since the inductance components of this structure use enamelled copper wires, the production cost is high. For example, when the enamelled copper wire head is changed to aluminum wire, it is easy to appear that the welding is not firm,...
